ITP62 Data Description

The ITP profiler was configured to operate on a standard sampling schedule of 2 one-way profiles between 7 and 750 m depth each day. In the surface package, the GPS receiver was powered hourly to obtain locations hourly, and buoy temperature and battery voltage status were recorded.

The buoy initially meandered in circles then headed southward approximately along 135 W longitude, then headed west between 74 N to 72 N before encountering the slope near Barrow Canyon where the anchor apparently dragged the bottom. Fortunately the system then headed north along 155 W and resumed profiling until it encountered the shallow bathymetry along the Northwind Ridge. The profiler continued to communicate data to the surface package until the Iridium transmissions ceased in August.

The plots to the right are of the final, calibrated, edited data (as opposed to the raw data presented on the active instrument pages).
See the Data Products tab to the left for descriptions of the three levels (I, II, III) of data processing and to access all data.
